The NTT Group is involved in a number of efforts to avoid such environmental risks as environmental accidents and pollution that could cause major losses and damage to society.
We are committed to preventing accidents and pollution through regular soil and water surveys, chemical management, removal and storage of items using PCB, and the like, in accordance with our guidelines.
In fiscal 2004, however, we had an accident in which wastewater including alkaline waste liquid erroneously leaked to a general river and the wastewater criteria of the Water Pollution Control Law was surpassed. We quickly remedied the problem and put measures in place to prevent a re-occurrence, including a revision of our detection and alarm system and our daily inspections and work procedures.
Studies on the Impact of Radiation from Mobile Phones on Living Organisms
 A Cell Experiment
Our four mobile-phone carriers have been studying the affects of radiation from mobile phones on living organisms since 2002. As part of these studies, in April 2004 Mitsubishi Chemical Safety Institute Ltd. reported the results of an experiment on cells conducted on contract from NTT DoCoMo.
According to the report, "It was found that the radiation from mobile-phone base stations have absolutely no affect on the proliferation or related genetic behavior of cells, which form the building block of life." In experiments before this one, there had been no hard evidence on the affects of this radiation on the proliferation rates, genetic behavior, breaks in the DNA chain, or the like in cells, but NTT DoCoMo set strict conditions on the intensity of radiation from its mobile-phone base stations, in the range of the protection guideline value to 10 times that level. It also contracted studies on nearly half of the roughly 40,000 genes commonly working in the human genome.
NTT DoCoMo plans to continue with these types of cell experiments, and continue to publish their results.
NTT Communications Embarks on a New Service to Support Green Procurement Management and Chemical Content Management
In February 2005, NTT Communications started "Green Procurement Support Services" in response to the EU's restriction on chemical substances contained in products.Electric and electronics industries worldwide are actively participating in the green procurement that focus on compliance with European environmental regulations, such as RoHS, ELV, WEEE directives.
With NTT Communications' new services, companies that design, manufacture or market product will be able to analyze or detect hazardous chemical substances in products. Moreover, companies can globally use such chemical contents as green procurement data, chemical substance data and environmental regulations.On the strength of each field of expertise, from information service technology to chemical analysis, the Green Procurement Support Services enable users to make content-processing requests over the Internet, through a Web interface.
Major possible users of this service are assemble/set manufactures, parts/components manufactures and chemical/material manufactures, supplying electrical and electronic products.
